Preserved Implicit Semantic Differentiation in an Alexic Wernicke's Aphasic
… 3 tasks: a 2-category, non-semantic visual oddball; a 3-category, semantic visual oddball; and a word-to-picture card-sorting task. ERPs collected during the oddball tasks were analyzed using the bootstrap method, a non-parametric technique for estimating a population distribution from a …

An ERP Study to Investigate Age-Related Differences in Sensory Gating and Auditory Processing
… effect of age on adaptive gating responses for oddball stimuli. Age-related differences in sensory gating and oddball responses were observed in late-stage auditory processing, where older adults exhibited weaker sensory gating. An attenuated P200 for firstandsecond clicks seen in the aging …

Examining Face Perception with Self-Reports and Neural Measures: An SSVEP study
… a different face or object appeared. This oddball stimulus, inserted among the base-level stimuli, was presented at a frequency of 1.2 Hz. It differed primarily from the standard stimulus in higher-level characteristics, making it ideal for assessing higher-level visual processes. The …

Synchronized Gamma Oscillations Underlying Mid-latency Auditory Evoked Potentials: Assessment of Effects of Psychopharmacologically Active Components of Tobacco
… were examined in two paradigms: paired-tone and oddball. During a paired-tone paradigm, our previous work (Crawford, McClain-Furmanski, Castagnoli, & Castagnoli, Neuroscience Letters 317(2002) 151-155) found heavy smokers exhibited chronic (rather than acute) effects in the frontal region: (1) …

The facial inversion effect throughout healthy adult aging : an event-related brain potential study
… dementia. In this research, a sequential imaging oddball paradigm that utilizes upright and inverted familiar and unfamiliar faces were used to scrutinize the effect of facial inversion throughout healthy adult aging. The results indicate that late event-related potentials such as the P300 and …

An exploration of pre-attentive visual discrimination using event-related potentials
… clinical groups. A three stimulus visual oddball paradigm was used to explore the elicitation of visual discrimination components to a change in the orientation of stimuli in the absence of a behavioural task. Monochrome stimuli based on pacman figures were employed that differed from each …

Fúze simultánních EEG-FMRI dat za pomoci zobecněných spektrálních vzorců
… pro relativní pásmo pro data vizuálního oddball experimentu. Pro EEG-fMRI data s úkolem sémantického rozhodování, frekvenční závislost nebyla ve finálních výsledcích tak evidentní, neboť všechna pásma zobrazily vizuální síť a nezobrazily aktivace v řečových centrech. Tyto výsledky byly …

Subjective, behavioural and electrophysiological measurements of the time-course and intensity of sleep inertia after a full night of sleep /
… tone also served as the target stimulus for an oddball task designed to examine the NlOO and P300 components ofthe ERP waveform. The five-minute oddball task was presented at 15-minute intervals over the initial 90-minutes after awakening to obtain six measures of average RT and amplitude and …

Developmental and individual differences in novelty and error detection in 10-year-old children and young adults /
… of novel stimuli during an auditory novelty oddball task, and error detection during a visual flanker task. All participants showed a parietally-maximal P3 in response to auditory stimuli. In children, novel stimuli generated higher P3 amplitudes at the frontal site compared with target …

THE EFFECTS OF AN ACUTE BOUT OF EXERCISE UPON BEHAVIORAL RESPONSES TO AND NEUROPHYSIOLOGICAL INDICES OF ATTENTION ALLOCATION IN CHILDREN AND ADULTS
… of age) who completed a 3-stimulus auditory oddball behavioral task, pre- and post-exercise intervention. Results: Contrary to expectations, this study found that, regardless of age, engagement in an acute bout of exercise did not have a significant effect upon some behavioral and all …

N200 and P300 Evoked by Stimuli Straddling Category Boundary in Lexical Context
… was selected as the deviant in an active oddball paradigm commonly used to obtain N200 and P300 ERPs. After subjects finished a two-forced choice labeling test, they participated in electrophysiological testing while simultaneously pressing a response button when they heard the deviant …

Attentional Bias to Alcohol-related Cues in Social Drinking College Students
… Participants performed a computerized, visual oddball target detection task in which they were asked to react to specific target pictures (either alcohol-related or neutral objects) before and after an acute stressor (timed mental arithmetic). Stress levels were measured via self-report …

Mismatch Negativity as a Marker of Auditory Pattern Separation Integrity in Aging
… (55–86 years, 14 females) adults in a passive oddball paradigm using tone sequences. Participants then completed an incidental recognition test for old targets against similar lures and dissimilar foils. Older adults showed attenuated MMN amplitudes and poorer performance discriminating targets …

P300-Based BCI Performance Prediction through Examination of Paradigm Manipulations and Principal Components Analysis.
… of a predictive relationship between traditional oddball tasks and BCI performance. Both waveform and component analysis have revealed several task-dependent aspects of brain activity that show significant correlation with the user's performance. These components may provide a fast and reliable …

Working memory and neuroplasticity in older people: a behavioural and neurofunctional approach
… a continuous performance task and a visual oddball paradigm while EEG was recorded. They were divided into high-performance (HP) and low performance (LP) groups according to their performance in the Raven’s Advanced Progressive Matrices test (RAPM). HP group presented significant higher LPC …
